The modeling of vehicle automatic clutches driven by brushless DC motor has to encounter complexities due to nonlinearities and uncertainties in a vehicle dynamic system. In this paper, a nonlinear robust controller was developed by means of the variable structure control to improve control responses of an automatic clutch. Computer simulations are made for an actual automatic clutch system and the numerical results obtained from the presented control method shows that the variable structure control method is characterized with robustness in varying parameter of the system and efficient in forcing the automatic clutch system motion to track the specified trajectories.
